You have to wait for servers to update. In the past, it wasn't a problem (heck if you didn't upgrade the hour of the release, you couldn't play anywhere), but now there's so few download sites to choose from. And out of those, fewer work properly or have faster download rates.
I'm disappointed with Valve on the new patch for the amount of time spent on it. Seems quite unstable, breaks OpenGL for Radeon users, breaks most mods (except Counter-Strike, surprise? We think not), and the VoiceCom sounds terrible (like most VoiceCom programs). As for CS 1.3, I'm sure it'll be the same old gameplay as before, with the same old bunnyhopping (yes it's still here!). Hoo-Ha!
I'd expect another patch soon.
